Mucus Plug

I just got out of the shower and put new underwear on, about 5minutes after I went to the bathroom to go pee, and I looked into my underwear and it was wet with kinda clear white slimy stuff in it. Is it part of my mucus plug? I don't remember loosing my mucus plug with my daughter 4yrs ago. I am 37weeks and 1 day. I am due to have my c section in 2 weeks unless my son comes early.
